' Application filed July 31, 1915. Serial No, 42,995.

To all whom it may concern:

Beit known that I STANLEY ALDER, subject of the King of Great Britain, residing at 78 Dundas street,-- Sunderlandfin the county of Durham, England, have invented certain new and useful Improvements in Explosion-Engines, of which the followv ing isa specification.

' further,

' production in The invention relates to an explosion engine, and provides therein and therewitha combin'ationof parts-efficiently utilizing the exhaust gases and some of the heated water erator is supplied to the explosion engine to aid internal coolingenrich the mixture and and expansion. A further combined feature in the engine is a vacuum jacket surroundmg the steam generator and steam engine either wholly or in part to prevent external radiation.

The improvements, are diagrammatically illustrated by the accompanying drawing showing in vertical section a simple application of the combined features aforesaid applied to. an engine of two-stroke cycle.

.The explosion cylinder represented at a and c, and'the water jacket surrounding said cylinder and part of the valve pockets at cl. The cool suitably forced into the jacket 0! through the supply passage 0?, and leaves said jacket mainly through the outlet 11 in connection with which outlet is provided a suitable throttle 0Z for producing a back pressure on the outflow of the cooling water to permit of the cooling 'yvater in said jacket d being heated to the highest possible temperature consistent with explosion engine. citand 03 are gas and air admission valves to the explosion cylinder a, and c is an admission valve for Wet steam into said cylinder, each valve being mechanically operated to open in suitable and known manners.

The steam valve e controls the admission to the cylinder, a, of steam raised in a Specification of Letters Patent.

For the generation of steam the generator is supplied with the hottest water leaving the water jacket d by the pump 2' and valve arrangements j. The pipe i conducts water through the non-return valve j? to the pump 2', and the pipe 5 conducts said water from thel pum'p through the non-return valve j to tlfie generator f.

being suitably cone pump c is driven from the crank slide valve Z working within a steam: chest Z Said steam chest is suppliedwith steamf from the generator f'by a pipe Z. The slide valve Z controls inlet of a steam cylinder with the explosion the vacuum jacket it, diameter piston 0 with the explosion and exhaust ports a u and fitted with a large reciprocating as one piece piston c, to thereby incor- 0 arranged concentric" 7 cylinder at and within porate with the explosion engine a steam engine.

1 By such combination of parts the hottest T water in, the cooling jacket, and the hcatin the exhaust gases, are utilized in a steam generator inclosing the water acket for the purpose of raising steam to be used as part 7 charge, if desired, to enrich of the explosive the mixture and aid internal cooling and expansion of the exhaust gases, and as the motive power in a steam engine incorporated with the explosion engine.

' and in conjunction with instant the slide valve Z is reversed so also are the valves 6, dtand 03 Having now described my invention what I claim and desire to secure by Letters Patent is 1. The combination with an explosion en.-

gine having a water cooling jacket, of a nencommunicating steam generator surrounding said jacket, means arranged within said generator and connected to receive exhaust gases from the engine and to circulate the same within said generator for steam production therein, and means connected to receive heated water from said cooling jacket and operative to introduce such water into said steam generator.

2. The combination with an explosion engine having a water cooling jacket, of a steam generator surrounding said jacket but non-communicating relatively thereto means arranged within said generator and connected to receive exhaust gases from the engine and to circulate such gases within the generator for steam production there on, means connectedto receive heated water from the cooling jacket and to introduce the same in the steam generator, and a steam engine incorporated as a part Working with cylinder steam cylinder,

the explosion engine and operative by steam supplied thereto from said generator,

3. The combination with an explosion ongine having a water cooling jacket, oi a steam generator surrounding said. jacket but non-commuuicating relatively thereto, means arranged within said generator and connected to receive exhaust gases from the engine and to circulate the same within the generator for steam 'n'mluction thereon, means connected to receive heated water from the jacket and operative to force the same into said gcnerati'ir, a steam engine incorporated as a part working with the explosion engine and. operative by steam supplied thereto from the steam generator, and means for supplying steam from the generator to the explosion engine as part of the charge thereof.

ti. The combination with an explosion engine having a water cooling jacket, of a steam gei'ierator surrounding said jacket but non-communicating relatively thereto, means arranged within the generator and connected to receive exhaust gases from the engine and to circulate the same within the generator for steam production therein, means connected to receive heated water from the cooling jacket and operative to introduce the same into the steam generatonaud a vacuum jacket arranged externally of the explosion and generator to prevent radiation.

In testimony whereotl. I have hereunto set my hand in presence of two suliscribing witnesses.
